Sovereign programs are characteristically used for long, continuous stretches of time. A sovereign program dominates a user's workflow as his primary tool

3: What are the requirements framework elements of websites?

4: What are controllable vocabularies?

Vocabulary control comes in many shapes and sizes. At its most vague, a controlled vocabulary is any defined subset of natural language. At its simplest, a controlled vocabulary is a list of equivalent terms in the form of a synonym ring, or a list of preferred terms in the form of an authority file.

5: Explain two types of methods to eliminate error messages?

Making it impossible for the user to make errors is the best way to eliminate error messages. By using bounded gizmos for all data entry, users are prevented from ever being able to enter bad numbers. Instead of forcing a user to key in his selection, present him with a list of possible selections from which to choose. Instead of making the user type in a state code, for example, let him choose from a list of valid state codes or even from a picture of a map. In other words, make it impossible for the user to enter a bad state.

Another excellent way to eliminate error messages is to make the program smart enough that it no longer needs to make unnecessary demands. Many error messages say things like " Invalid input. User must type xxxx." Why can't the program, if it knows what the user must type, just enter xxxx by itself and save the user the tongue-lashing? Instead of demanding that the user find a file on a disk, introducing the chance that the user will select the wrong file, have the program remember which files it has accessed in the past and allow a selection from that list. Another example is designing a system that gets the date from the internal clock instead of asking for input from the user.

6: describe the process of data collection with respect to notes and use of camera?

Notes plus still camera

Taking notes is the least technical way of collecting data, but it can be difficult and tiring to write and observe at the same time. Observers also get bored and the speed at which they write is limited. Working with another person solves sonic of these problems and provides another perspective. Handwritten notes are flexible in the field but must be transcribed. However, this transcription can be the first step in data analysis, as the evaluator must go through the data and organize it. A laptop computer can be a useful alternative but it is more obtrusive and cumbersome, and its batteries need recharging every few hours. If a record of images is needed, photographs, digital images, or sketches are easily collected.

7: what is global navigation and its components?

10: What is the widespread misconception about the error

messages? 2

This is a widespread misconception. Most error message boxes are informing the user of the inability of the program to work flexibly. Most error message boxes seem to the user like an admission of real stupidity on the program's part.

11: Briefly explain, why do people hate error messages? 2

Humans have emotions and feelings: Computers don't. When users see an error message box, it is as if another person has told them that they are stupid. Users hate this.

12: In evaluation process, tells about schedule and budget constraints. 5 Time and budget constraints are important considerations to keep in mind. It might seem ideal to have 20 users test your interface, but if you need to pay them, then it could get costly. Planning evaluations that can be completed on schedule is also important, particularly in commercial settings. There is never enough time to do evaluations as you would ideally like, so you have to compromise and plan to do a good job with the resources and time available.
